mc4558cdt.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

MC4558CDT

STMicroelectronics · Operational Amplifier · SO-8

MC4558CDT from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Output 1 output Op-amp A output. Class-AB push-pull output stage with short-circuit protection; typical output resistance 75 Ω, output short-circuit current 20 mA typ.
2 Inverting input 1 input Op-amp A inverting input (IN-). High-impedance bipolar input; typical input bias current 50 nA, input resistance 2 MΩ typ.
3 Non-inverting input 1 input Op-amp A non-inverting input (IN+). Common-mode input range ±12 V typical at Vcc = ±15 V.
4 VCC- power_in Negative supply rail. Supply voltage range ±2 V to ±20 V (absolute maximum ±22 V). Shared between both op-amps.
5 Non-inverting input 2 input Op-amp B non-inverting input (IN+). Common-mode input range ±12 V typical at Vcc = ±15 V.
6 Inverting input 2 input Op-amp B inverting input (IN-). High-impedance bipolar input; typical input bias current 50 nA, input resistance 2 MΩ typ.
7 Output 2 output Op-amp B output. Class-AB push-pull output stage with short-circuit protection; typical output resistance 75 Ω.
8 VCC+ power_in Positive supply rail. Supply voltage range ±2 V to ±20 V (absolute maximum ±22 V). Typical total supply current 2.3 mA (both amplifiers, no load).

CAD (KiCad official)

  • Symbol: MC4558CDT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: mc4558cdt-etched.step / mc4558cdt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc4558cdt.step / mc4558cdt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mc4558cdt.step 122 KB You want the bare part, or you mark your own boards.
mc4558cdt-etched.step 2.0 MB You want the part with MC4558CDT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 484 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
